Will Mesa/Gallium3D Work With The Open-Source Doom 3?

Phoronix: Will Mesa/Gallium3D Work With The Open-Source Doom 3?

With the release of the Doom 3 source-code coming up soon (after John Carmack is done addressing a patent issue), it's time to begin dusting off your old id Software Doom 3 DVD/CDs and/or get ready to begin developing new content and games on the id Tech 4 engine. If you're wondering whether or not the open-source Mesa/Gallium3D Linux drivers in 2011 will now work with the id Tech 4 game from 2004, here are some tests of the very latest open-source Intel, ATI/AMD, and NVIDIA drivers under Ubuntu Linux.

"To sum up the situation for now, if wanting to run Doom 3 on open-source Linux graphics drivers, the best performance and stability is for now with the Radeon Gallium3D stack. There was never any lock-ups or other issues like was common for Intel and their classic Mesa driver on Sandy Bridge. Nouveau Gallium3D was also quite decent, but there seems to be a problem in the Fermi Gallium3D component delivering awful performance and overall the Nouveau support tends to be less optimized as AMD's open-source offering."

because of this i only buy amd hardware.

for me there is no point in using an Intel graphic card or a nvidia one.

I would not use nouveau for long time as the binary driver is much better, i tested it a few month ago however. intel users can not switch, but i. e. xbmc can use vaapi acc with full h264 l5.1 support where even fglrx fails (via xvba wrapper). if you have got a strong cpu when maybe use ati oss, but for me thats pointless especially with a fast ati card - you lose so much speed and opengl features.

"if you have got a strong cpu when maybe use ati oss, "

the point is you can use a strong cpu.
right now i use a phenomII x4 3,9ghz. (x2 b50)
this cpu only cost you maybe 50-60€ on ebay.
no problem.

i don't get the point why not spend 60€ for a cpu for opensource linux ??
other people spend this on 1 ride in a whorehouse.
